Abstract

Cette invention concerne un dispositif rotatif servant à disperser un gaz présent dans un métal en fusion. Le dispositif comprend un puits creux (20) à une extrémité duquel est fixé un rotor (22). Le rotor (22) présente un toit (24) et une base (26) espacés l'un de l'autre et reliés par plusieurs aubes (32). Un compartiment (34) est délimité entre chaque paire d'aubes (32) adjacente et le un toit (24) et la base (26), et chaque compartiment (34) présente un orifice d'entrée (36) et un premier et un second orifices de sortie (38, 40). Le puits (20) est traversé d'un circuit d'écoulement qui passe par les orifices d'entrée (36) des compartiments (34) pour déboucher sur le premier et le second orifices de sortie (38, 40). Chaque premier orifice de sortie (38) est disposé radialement vers l'extérieur de l'orifice d'entrée (36) respectif et arrangé pour disperser le gaz latéralement, depuis le rotor (22), pendant l'utilisation; et chaque second orifice de sortie (40) est disposé dans le toit (24) du rotor (22) et arrangé pour disperser le gaz vers le haut, depuis le rotor (22), pendant l'utilisation.
